Which FRX Projector ?

[Pdwight]

I am thinking about retro fitting a set of FX-R projectors in my 01 S , my question is which ones ? I see FX-R 2.5 and FX-R 3. Also can I make the entire thing self contained with no outside wiring....I see some who have added a relay and wiring and I wonder why with all that room in the light fixture ??

Also 35 W or 55W as I do most of my driving in the country and only on weekends....have a boring Honda CRV for daily use.

Thanks in advance
